I’ve recently been trying to improve the performance of the
Vertica replicator, particularly in the form of the of the new
single schema replication. We’ve done a lot in the new Tungsten Replicator
5.3.0 release to improve (and ultimately support) the new
single schema model.

As part of that, I’ve also been personally looking to Kodiak MemCloud
as a deployment platform. The people at Kodiak have been really
helpful (disclaimer: I’ve worked with some of them in the past).
MemCloud is a high-performance cloud platform that is based on
hardware with high speed (and volume) RAM, SSD and fast Ethernet
connections. This means that even without any adjustment and
tuning you’ve got a fast platform to work on.

However, if you are willing to put in some extra time, you can
tune things further. Once you have a super quick …

“Spark and Ignite can complement each other very well.
Ignite can provide shared storage for Spark so state can be
passed from one Spark application or job to another. Ignite can
also be used to provide distributed SQL with indexing that
accelerates Spark SQL by up to 1,000x.”–Nikita Ivanov.

I have interviewed Nikita Ivanov,CTO of GridGain.
Main topics of the interview are Apache Ignite, Apache Spark and
MySQL, and how well they perform on big data analytics.

development projects?

Nikita Ivanov: SaaS requires that the applications be highly
responsive, reliable and web-scale. SaaS development projects
face many of the same challenges as …

“After you have built out your data lake, use it.
Ask it questions. You will begin to see patterns where you want
to dig deeper. The Hadoop ecosystem doesn’t allow for that
digging and not at a speed that is customer facing. For that, you
need some sort of analytical database.”– Eva
Donaldson.

I have interviewed Eva Donaldson, software
engineer and data architect at iContact. Main topic of the interview is her
experience in using HPE Vertica.

Practical tips and a live demo of how to get your data warehouse
loading projects off the ground quickly and efficiently when
replicating from MySQL and Oracle into Amazon Redshift, HP
Vertica and Hadoop.

Oracle's expensive and complex replication makes it difficult to
build cost-effective applications that move data in real-time to
data warehouses (Oracle, Hadoop, Vertica) and popular databases
like MySQL. Fortunately, Continuent Tungsten offers a solution.In
this virtual course, you will learn how Continuent Tungsten
solves problems with Oracle replication at a fraction of the cost
of other

Over the last few years there has been an increasing interest in
immutable data management. This is a big change from the
traditional update-in-place approach many database systems
use today, where new values delete old values, which are then
lost. With immutable data you record everything, generally using
methods that append data from successive transactions rather than
replacing them. In some DBMS types you can access the older
values, while in others the system transparently uses the old
values to solve useful problems like implementing eventual
consistency.

Baron Schwartz recently pointed out that it can be hard to get
decent transaction processing performance based on append-only
methods like append-only B-trees. This is not a very
strong argument against immutable data per se. …
